| 摘 要： | 前文曾报导铜(Ⅲ)-N-(取代苯基)亚氨基二乙酸-α-氨基酸三元混配型配合物的稳定性与配位体的酸碱强度之间的直线自由能关系,其中铜(Ⅱ)与N-(取代苯基)亚氨基二乙酸仅形成1:1型二元配合物,且α-氨基酸为二齿配体,数据处理为半整数法.为了进一步探讨配合物中的直线自由能关系的普遍性,本文以镍(Ⅱ)、钴(Ⅱ)、锌(Ⅱ)与N-(对和间位取代苯基)亚氨基二乙酸(RPhIDA;R=CH_3O、CH_3、H、Cl)(三齿配体)形成1:2型二元配合物及其与氮三乙酸(NTA)(四齿配体)形成三元配合物来研究此配合物的稳定性与配体酸碱强度之间的直线自由能关系.数据处理采用非线性最小二乘方拟合的TITFIT 程序进行.

| Abstract: | The stability constants of binary complex eompounds formed by Ni(Ⅱ), Co(Ⅱ), Zn(Ⅱ)-N-(meta or para substituted phenyl) Iminodiacetic acid (m or p-RPhIDA) and of ternary complex compounds formed by Ni(Ⅱ), Co(Ⅱ), Zn(Ⅱ)-RPhIDA-Nitrilo-triacetic acid (NTA) were determined by pH method at 25±0.1 ℃ in the presence of 0.1 mol·dm~(-3)BaC_(10)_4. Their results were calculated by TITFIT program. It was found that linear free energy relationships did exist between the stability of there binary and ternary complex compounds and the base strengths of Ligands RPhIDA. |
